Parts for your 1998 Mitsubishi Pajero-Exhaust mount

1998 Mitsubishi Pajero exhaust-mount — what it does and how to keep it sorted

Yes, an exhaust-mount (often called an exhaust hanger or insulator) is absolutely fitted to the 1998 Mitsubishi Pajero. This isn’t guesswork — it’s shown in Mitsubishi’s factory documentation for the V2# series (1997–1999) in Group 15A – Exhaust System, where multiple rubber insulators are specified at the front pipe, centre and rear mufflers. The Mitsubishi ASA electronic parts catalogue for 1998 Pajero models (e.g., V25W/V45W) lists “Insulator, exhaust mounting” with common part numbers such as MB687013, MR127472 and MR127520 across petrol 6G74 and diesel 4M40 variants. These technical sources confirm the mounts are standard hardware on this vehicle.

On the Pajero, exhaust-mounts support the weight of the exhaust while isolating vibration and engine movement from the cabin. They let the system flex over bumps and during torque roll without cracking pipes or stressing the manifold and turbo hardware (on diesel models). When they’re in good nick, you get fewer rattles, less droning and better clearance to the chassis, crossmembers, towbar and rear bumper.

Because they live under the car in heat, road grime and mud, the rubber ages and softens. Oil contamination, UV and off-road use speed this up. At regular services (every 10,000–15,000 km or six months, in line with typical local schedules), it’s smart to check each mount for:

• Cracks, splits, elongation of holes or obvious sag
• Excess exhaust movement, knocks over bumps or a tailpipe that sits off-centre
• Heat-hardening near the front pipe or turbo area and perished rubber near the rear muffler

Replacement is straightforward: support the exhaust with a stand or jack, soak the old mounts and studs with penetrant, then lever the insulators off. A dab of silicone spray helps the new ones slide on. Choose quality OEM-style rubber for factory NVH, or heavy-duty/polyurethane mounts if the Pajero tows, runs bigger tyres or sees corrugations. After fitting, make sure there’s even clearance to the body, suspension and towbar, and re-check after the first heat cycle.

Handy tips for Pajero owners:

• Replace in pairs if one has failed — the rest won’t be far behind
• Inspect brackets and welds, a torn bracket will eat new rubbers quickly
• A quick check of heat shields stops future rattles

These small rubber mounts do a big job. Keeping them fresh protects the rest of the exhaust and keeps the big Mitsi quiet and comfy on long Kiwi or Aussie runs.

Popular questions

How often should exhaust-mounts be replaced on a 1998 Pajero?
There’s no fixed interval, but checking them at every service (about every 10,000–15,000 km) is wise. In hot climates, with towing or off-road use, expect to replace them more frequently as heat and load accelerate wear.

What are the signs the exhaust-mounts are failing?
Look for new knocks or rattles over bumps, a tailpipe sitting lower or skewed, droning at certain revs, or visible cracks and stretched holes in the rubber insulators.

Is polyurethane better than rubber for Pajero exhaust-mounts?
Poly mounts can last longer and control movement better for towing or heavy off-road work. For everyday driving, quality rubber keeps factory-level comfort and noise control.
